WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,687, dated May '7, 1889.

Serial No. 270,666. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. ROBERTS, a citizen of the United States of America, and a resident of Panora, in the county of Guthrie and State of Iowa, have invented an Improved ashing-Machine, of which the following is a specification.

My invention consists in the construction device with a tub, as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a top view, and Fig. 2 a longitudinal and vertical view through a central line, of the tub, presser device, and wringer. Fig. 3 is a perspective view showing the presser device reduced in size. Fig. at is a perspective view of the complete machine.

A represents a tub of quadrangular shape, that may vary in size as desired.

B B are sections of a cover hinged to the opposite sides and top edges of the tub.

O is an opening in the cover, through which the handle of the presser device projects and moves.

D is a sliding cover over the opening 0.

F is my presser device, cast complete in one piece and galvanized or made of metal alloy that will not corrode. It is in the form of an arc, and has a series of open-bottomed air cups or chambers on its under side. Its ends and sides are closed, and journals or gudgeons g project outward in opposite directions from its sides and center, as shown in Fig. 3, to enter grooves or bearings h, formed in or fixed to the inside faces of the sides of the tub.

i 1' are perforated lugs on the ends, adapted to receive and retain the ends of a forked handle, J, that extends up through the opening D.

K is a hand-lever hinged to the handle J in such a manner that the handle can be thereby vibrated, as required, to rock the pressing Heretofore a rocking rubber having a concave wooden bottom has had flanges fixed to its under side to produce chambers, and a handle to its top and centerin such a manner that it would have a longitudinal movement in a tub at the same time it was rocked. My

manner of casting a rocker complete in one the weight of the metal rubber Will produce sufficient pressure upon the articles to be washed, its perforated ears facilitate the attachment of a forked handle, and its journals facilitate its rocking motion and prevent any sliding motion that would injure the fabric subjected to its action.

L is a metal frame and tub-brace cast complete in one piece,- and adapted to re-enforce' the tub, and also to support a wringer. It has integral angle-irons m, that fit over the corners of the tub and adapt the complete brace to be readily fixed to the outside and top of the end of the tub by means of screws.

In the practical operation of my machine I place water in the tub and under the pressure device, and then rock the presser and airforcing device by imparting a reciprocating motion to the hand-lever. The gudgeons on the sides that extend into the vertical bearings in the tub allow the device to rock and to rise and lower at each motion, but prevent it from moving away from the center of the tub. At each motion the ribs on its bottom or the edges of the air-chambers press upon the fabric underneath, and at the same time force the air confined in the cells or chambers through the water and meshes of the ar-v ticles, as required, to remove the dirt therefrom.

I claim as my invention- A metal rubbing device of concavo-convex form, having open chambers or cells on its convex surface, integral perforated lugs on its ends, a forked handle attached to said lugs, and integral journals on its edges, in combination with a tub having grooves in the inside faces of its parallel sides, for the purposes stated.
